Class Base64

  ice.util.encoding.Base64

public class Base64

extends Object

This Base64 is a utility class for encoding and decoding using the Base64 encoding. Additionally, it contains other handy methods.

The Base64 encoding is designed to represent arbitrary sequences of octets in a form that need to be humanly readable. The encoding and decoding algorithms are simple, but the encoded data are consitently only about 33% larger than the unencoded data.

For more complete information about the Base64 encoding, please read MIME (Multipurpose Internet Mail Extensions) Part One (Section 5.2).
